Could you build this?

Partial Upload, link sharing, and slide sync are buildable, but live cursors, shared control, and pen/laser overlays need real-time synchronization that vibe coding won't get right alone.

What it would actually take: Use PDF.js or a server-side converter to render slides to images, then sync state over WebSockets or WebRTC data channels (for example, Yjs or Liveblocks-style CRDTs for cursors and annotations). Permission handling and reconnection logic need care, and the system must stay responsive for large audiences. Real-time systems and conflict-handling experience is needed, along with infrastructure to keep latency low at scale.
